A 20-year veteran's 12-layer engineering stack for production AI agents
MaryamMiradi · x · 2026-10-22
Maryam Miradi, claiming 20+ years in AI and 400+ production agents, shares her 12-layer agent engineering stack, using a medical emergency agent as the example:
- Business engineering: define the decision — who needs urgent care?
- Data understanding: check quality and completeness (missing allergy records?).
- Knowledge engineering: ground decisions in medical guidelines and patient history.
- Context engineering: supply the right information (chest pain vs. ankle injury).
- Model engineering: pick the right model per task (classifier vs. LLM).
- Semantic engineering: understand domain language (MI = myocardial infarction).
- Agent engineering: route tasks to the right specialist agent.
- Loop engineering: build verification and correction loops (thread truncates here; remaining layers not shown).
